Abstract: A coin validator (10) has a coin path (26) which passes between one set of detect coils (40, 42). The set a of coils (40, 42) is connected in a detect circuit, and the coils (40, 42) are adapted to be energised with a single pulse. The decay curve (70) of the voltage in the coils (40, 42) is processed to pro-duce a set of three numbers of clock counts defining each coin; which are stored in a microprocessor. pre-programming of the valida-tor ( 10) involves generating sets of numbers for repres-entatives of a coin type to create three ranges of num-bers, within which respec-tive range subsequent coin's set of numbers must fall in order for it to be defined as an example of the coin type. The coin path (26) is arranged at an angle to the vertical, and the base (32) is arranged at an angle to the horizontal such that the angle between one wail (36) and the base (32) is between 90° and 180°, causing coins passing along the coin path (26) to orient themselves such that each of them has point contact on the base (32) and on the one wall (36), thereby occupying a generally similar position with respect to the coils (40, 42).

Granted: 1999-01-12
Abstract: A method of selecting handover targets for a communication unit (40) exchanging a communicated signal through a serving base site (10-19) in a digital cellular system. The method uses timing advance to determine a relative distance of a communication unit (40) to the serving base site (10-19). The method comprises the steps of comparing a timing advance value with a first threshold. The first threshold may be equal to a distance one and one-half times the radius of the serving cell. When the timing advance value exceeds the first threshold, a base site frequency list is modified to include base sites non-adjacent the serving base site. The identity of the base sites non-adjacent the serving base sites may be determined from the directionality of communication unit (40). The method further includes the step of selecting a handover target providing highest relative RRSI value to the communication unit (40) from the modified base site frequency list.

Granted: 2005-09-13
Abstract: A method and apparatus for continuously monitoring cardiac output based upon phase shift between an input signal and a temperature signal indicative of change in blood temperature leaving the heart. In a preferred embodiment of a cardiac output monitoring system (10), a catheter (14) is provided with an electrical resistance heater (22). An electrical current having a sinusoidal wave form with a period of from 30 to 60 seconds is applied to the heater, causing power to be dissipated into the blood within a patient's heart (12). A  temperature sensor (24) disposed near the catheter produces a signal indicative of the temperature of blood leaving the heart. The temperature signal and the signal corresponding to the electrical power dissipated in the heater are filtered at a frequency .omega. corresponding to the frequency of the applied electrical current. The amplitude of the input power, the amplitude of the temperature signal, and their phase difference are used in calculating cardiac output.

Title: Hybrid human/porcine factor viii
Inventor: RUNGE MARSCHALL S
IPC: C07K19/00
Filed: 1993-04-07
Granted: 2002-07-02
Abstract: A hybrid human/porcine coagulation factor VIII is produced by isolation and recombination of human and porcine factor VIII subunits, or by genetic engineering of the human and porcine factor VIII  genes. Subunits of factor VIII that have been puri-fied from human or porcine plasma are isolated, and hybrid human/porcine factor VIII is produced by mixing either porcine heavy chain subunits with human light chain subunits or by mixing human heavy chain subunits with porcine light chain subun-its, thereby producing human light chain/porcine heavy chain and human heavy chain/porcine light chain hybrid molecules. These hybrid molecules are isolated by ion exchange chromatography.  Alternatively, recombinant DNA methods are used to swap elements of porcine factor VIII for the corresponding elements of human factor VIII to produce hybrid human/porcine fac-tor VIII.

Abstract: A post support includes a rectangular box section (1) which is open at at least one end (2) to receive a post, wherein the material of the box section (1) at a corner location of the box section is slit by spaced horizontal cuts (4a, 4b, 5a, 5b) in a plurality of axially spaced locations to provide either at least two spaced pairs of tabs or flaps (6, 7) of wall material, or a single pair of tabs or flaps (6, 7) positioned at a substantially central loca-tion axially of the box section, the free ends (8, 9) of which tabs or flaps (6, 7) are bent out-wardly away from the wall of the box section to form fixing flanges such that bringing to-gether of a pair of flanges by a fixing means, for example, a bolt (12) passing through holes (10) in said pair of flanges (8, 9), compresses the tabs or flaps (6, 7) inwardly of the wall of the box section (1) thus decreasing the cross-sectional dimensions of the box sec-tion (1) in at least two spaced locations or at a single substantially centrally positioned lo-cation, the material of the box section in said corner location being continuous except in the region of said tabs or flaps (6, 7). By means of the invention, an undersized post can be securely held within the box section (1). In the event of failure of the fixing means (10), the integrity of the box section (1) is maintained because the material of the corner of the box either is continuous at least in the region between two pairs of tabs or flaps (6, 7), and optionally also above and below each pair, or is continuous in the region above and below a single pair of tabs or flaps (6, 7). The post support of the invention will also normally have means for fixing it in or to a base support, for example an elongate member that can be driven into the ground, may be attached to the box section (1).

Abstract: Modem (12) comportant des raccordements (14, 16) aussi bien pour un téléphone à ligne terrestre (18) que pour un téléphone cellulaire (22). Ce modem comporte des sous-programmes de niveau supérieur et de niveau inférieur permettant d'accomplir rationnellement des ordres AT standards lorsqu'il est raccordé à un téléphone cellulaire et en outre, d'accomplir d'autres ordres AT donnant accès à des possibilités cellulaires spécifiques. Un programme logiciel d'applications dans un ordinateur relié au modem peut fournir un certain nombre d'options pour déterminer s'il est préférable d'utiliser la ligne terrestre ou le téléphone cellulaire lorsque l'un et l'autre sont raccordés. Dans un premier temps, il peut mettre hors circuit la ligne terrestre et n'utiliser que le téléphone cellulaire si la ligne terrestre n'est pas disponible. Selon une autre possibilité, il peut utiliser d'abord le téléphone cellulaire pour n'utiliser la ligne terrestre que si le signal de téléphone cellulaire n'a pas une force suffisante. En outre, les opérations de transfert cellulaire peuvent être interrompues si la puissance résiduelle des piles du téléphone cellulaire se révèle insuffisante pour achever de manière fiable ce transfert.

Title: Control apparatus for electric vehicles
Inventor: TANAMACHI TOKUNOSUKE
IPC: B60L9/18
Filed: 1995-09-01
Granted: 1999-03-23
Abstract: A control apparatus for controlling an electric vehicle, electric car, rolling stock or electric locomotive, which ensures an inverter output frequency command for its inverter not dependent on the rotor frequency of the induction motor, but controls the inverter output current by a constant current control system, thus preventing an overcurrent, and being capable of accelerating or decelerating the vehicle at a torque precisely corresponding to a current command.  The inverter output frequency command is modified to increment or decrement in accordance with a frequency-to-time rate-of-change command that has been updated by being controlled by the current control system.  Since the inverter output frequency command is basically not dependent on the rotor frequency of the induction motor, and since the output current of the inverter is controlled by the constant current control system, there are the advantages that an overcurrent is not likely to occur, and the vehicle can be accelerated or decelerated at a torque precisely corresponding to the current command.

Title: An electrical metering system having an electrical meter and an external current sensor
Inventor: COBURN DAVID CARL
IPC: G01R15/18
Filed: 1995-12-14
Granted: 2010-01-26
Abstract: An electrical metering system includes an electrical meter which is free of current sensors and an external current sensor for producing an output signal related to electrical current conducted by a transmission line to an electrical load associated with the electrical meter such that the power consumption of the electrical load can be computed by the electrical meter. The current sensor generally can include an unbalanced bridge circuit for producing a scaled output signal related, according to a predetermined ratio to the electrical current conducted by the transmission line. The electrical meter generally includes a register, responsive to the output signal produced by the external current sensor, to tabulate load data related to the power consumption of the associated electrical load. By employing an external current sensor capable of providing relatively large current transformation ratios, the electrical meter need not include a current sensor and the design of the electrical metering system can be greatly simplified.
